T0 at whom it may concern.-

Be it known that I, PETER KoNEs, a citizen of the United States,residing at Castlewood, in the county of Hamlin and State of SouthDakota, have invented certain new and useful Improvements in Wrenches;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such 'as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to wrenches, and more particularly to that type ofdevices of this character for use upon nuts.

The object of the invention is to provide a sliding jaw having a shankwhich is slidably mounted upon the shank of the stationary jaw and whichextends at all times into the handle, said sliding shank serving thepurpose of a reinforce for the stationary shank, so as to preventbending or breaking when subjected to unusual strain.

Another object is to provide novel means for locking the sliding jaw inadjusted position and additional means whereby the sliding aw can beadjusted either forward or backward by the fingers of the hand holdingthe wrench.

With the above and other objects in view the invention consists ofcertain novel features of construction and combination of parts, whichwill be hereinafter fully described, and pointed out in the claim.

In the accompanying drawings I have shown the preferred form of myinvention.

In said drawings, Figure 1 is a perspective view of my improved wrench;and Fig. 2 is a longitudinal section therethrough, the stationary shankbeing shown partly in section.

Referring to the figures by numerals of reference, 1 is a stationary jawfrom which extends a shank 2. This shank has a lateral enlargement 3adjacent one end, and a threaded stem 4 projects from said end of theshank and is adapted to receive a nut 5, whereby a grip 6 may besecurely fastened upon the shank. This grip is hollow, and the recess orpassage 7 formed therein is of such size as to receive the lateralenlargement 3, and when the shank 2 is secured within the passagesufficient space is left therein to receive a slidable shank 8, whichextends from and is integral with the sliding jaw 9 of the wrench. Thissliding jaw has an integral sleeve 10, which surrounds shank 2, and theend of its shank 8 is at all times within the passage 7 in grip 6. Shank8 is arranged parallel and in contact with shank 2, and its inner facehas a series of ratchetteeth 11 formed therein, which are adapted to beengaged by adog 12, which is pivoted within a passage 13, extendingthrough shank 2. A bow-spring 14 1s located within the passage 13 andbears upon the dog 12, so as to hold one end thereof normally in contactwith the toothed face of shank 8. The outer end of the dog 12 has anintegral shoulder 15, which serves to prevent the displacement of thespring 14 after the same has been properly inserted within passage 13. Alip 16 extends from shank 8 and is so located thereon that when the jaw9 is opened to its greatest extent the lip 16 will be exposed close tothe end of grip 6.

In using the wrench herein described the grip is held in one hand andthe dog 12 1s drawn inward by the first finger, so as to withdraw itfrom engagement with the ratchetteeth 11. By holding the wrenchvertically the sliding jaw 9 and its shank will then drop by gravity.Said sliding j aw can then be adj usted toward the fixed jaw 1 bypressing the thumb against lip 16, so as to move the shank 8 along shank2 and cause teeth 11 to slip from the dog 12. It will be obvious thatsaid dog will prevent the jaws from spreading apart as long as itengages one of the teeth 11. As the shank 8 extends from jaw 9 into thegrip 6 it will greatly reinforce the shank 2 and will prevent the samefrom breaking or opening when subjected to unusual strain, as when aheavy nut is being tightened.

The'wrench presents an attractive appearance, and considerableimportance is attached to the fact that the same can be adjusted andmanipulated by one hand.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

A wrench consisting of a fixed shank having a stationary jaw at one endand a grip at its other end said grip having a recess therein parallelwith the fixed shank, a aw slidably mounted upon the fixed shank, amovable shank extending from the slidable aw and projectinglongitudinally of the fixed shank and having teeth upon its inner face,a dog extending through the fixed shank and normally engaging the teethon the movable shank, a shoulder upon the dog, a bow-spring Within therecess and retainedby the shoulder, said spring holding the dog normallyin engagement with the teeth, said dog extending into close proximity tothe grip and a name to this specification in the presence of thumb-pieceupon the movable shank, said two subscribing Witnesses. do andthumb-piece extendin in opposite dii eotions from their shanks ari dadapted to PETER KONES 5 be simultaneously engaged by members of aWitnesses:

hand holding the grip. BERT MORGAN,

In testimony whereof I have signed my CAROLINE SHANKs.
